Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541094, here are decompositions:

23 + 31541071 = 31541094
43 + 31541051 = 31541094
47 + 31541047 = 31541094
73 + 31541021 = 31541094
103 + 31540991 = 31541094
173 + 31540921 = 31541094
223 + 31540871 = 31541094
227 + 31540867 = 31541094

Showing the first eight; more decompositions exist.
